SI8271GBD-IS

Isolators - Gate Drivers Overview

The SI8271GBD-IS is a single-channel, galvanically isolated gate driver from Skyworks Solutions. It utilizes silicon isolation technology to provide a high common-mode transient immunity (CMTI) of 2.5 kVrms. The device features a 3 V output supply voltage and includes an under-voltage lockout (UVLO) mechanism with deglitching capabilities for signal integrity. It operates within a temperature range of -40°C to +125°C and is housed in an 8-pin SOIC package.

Isolators - Gate Drivers Feature Summary

• High common-mode transient immunity via silicon isolation
• Integrated under-voltage lockout with deglitching
• Single-channel configuration for compact designs

Isolators - Gate Drivers Applications

• Automotive power electronics
• Industrial motor drives
• Switch-mode power supplies

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'GBD' against the manufacturer's official datasheet to confirm the inclusion of deglitching and UVLO specifications. Ensure the component meets automotive qualification standards if required by the target application. Cross-reference the pinout and thermal characteristics with the latest Skyworks documentation prior to integration.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed signal transmission across isolation barriers is critical. The integrated deglitching feature helps prevent false triggering in noisy environments. Consider the 3 V output level compatibility with low-voltage gate drivers. Evaluate the thermal performance requirements against the SOIC-8 package limitations for the specific PCB layout.

Isolators - Gate Drivers Part Context

This part belongs to the Si827x family of isolated gate drivers. It complements other variants like the SI8271GA-IS which may offer different isolation voltages or output drive strengths. The family focuses on providing robust isolation for modern power conversion applications where reliability and speed are paramount.

Isolators - Gate Drivers Replacement Considerations

Direct substitutes include other Skyworks Si8271 variants such as SI8271GBD-AS or SI8271GBD-ISR, provided they match the specific electrical characteristics and package type. Verify functional equivalence before substitution.
